Birgit R Tilley

Birgit R. Tilley serves as a Contract Specialist within Washington Headquarters Services (WHS), supporting the Department of Defense’s mission to streamline institutional operations through expert acquisition management. In this role, she manages the full lifecycle of procurement actions for mission-critical administrative and technical services, ensuring compliance with federal regulations and DoD acquisition policies. Her portfolio primarily encompasses consulting, IT modernization, and infrastructure support contracts that enhance enterprise efficiency and digital transformation across DoD components. Tilley’s work directly enables WHS to deliver high-impact, cost-effective solutions that sustain defense infrastructure and optimize resource allocation. She maintains established relationships with a core group of contractors including CLARITY INNOVATIONS LLC, CYNERGY PROFESSIONAL SYSTEMS LLC, SIGNATURE RENOVATIONS LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, and GUIDEHOUSE INC., all of which provide specialized management and technology services. These partnerships reflect a preference for experienced, non-traditional vendors capable of delivering complex, high-integrity solutions under tight operational timelines. Tilley’s contracting approach emphasizes performance-based outcomes, clear statement of work development, and rigorous contract administration to ensure deliverables align with strategic DoD objectives. Tilley’s procurement activity is exclusively conducted under full and open competition, with no set-asides utilized in her portfolio. This reflects a deliberate alignment with WHS’s enterprise-wide mandate to prioritize mission readiness and operational continuity over socioeconomic set-aside programs, though she remains compliant with all applicable small business reporting requirements. Her primary procurement focus lies in NAICS 541611 (Administrative Management and General Management Consulting Services) and NAICS 541618 (Other Management Consulting Services), which constitute half of her portfolio, alongside NAICS 541511 (Custom Computer Programming Services). She consistently acquires strategic advisory services, process optimization solutions, and tailored software development to modernize internal DoD systems, demonstrating deep expertise in enterprise management consulting and mission-critical IT modernization.
